sh Configure -des -Dcc="gcc -m32 -Dusethreads -Duserelocatableinc" -Dprefix=/usr/Thirdparty/perl/5.28.0/

There's no point in providing "-Dusethreads -Duserelocatableinc" as arguments for gcc to process. It won't understand them.
Run make distclean and try again with: 
sh Configure -des -Dcc="gcc -m32" -Dusethreads -Duserelocatableinc -Du
+selongdouble -Duse64bitint -Dprefix=/usr/Thirdparty/perl/5.28.0/

You could also try -Duse64bitall instead of -Duse64bitint.

Cheers,
